The largest study to date of recent military and veteran suicides has identified two high-risk groups of former troops who are generally ineligible for the psychiatric care afforded to all others who served: those forced out of the military for misconduct and those who enlisted but were quickly discharged for other problems.

In each of those groups, an average of 46 of every 100,000 former service members committed suicide each year — more than double the rate for veterans with honorable discharges.
